My N80 has mostly been working fine. I have adjusted the phone in the past couple of month so that battery life can last as long as possible, but recently the time to send sms has started to approach 30 seconds.

I can't spend 30 seconds each time I send a sms. No other phone functions are possible during this time. Does anyone have any idea what I can do about this?

I have tried to use a different sim-card, but still the same so it is the phone and not the operator. I thought about checking out a firmware-upgrade or something, but dunno how to do this. I did however restore factory settings at tools-settings-phone-general-operator settings (using the code 12345). This didn't have any effect.
